Title: Method and apparatus for purifying polymer
Inventor: TOYOSHIMA SHINICHI
IPC: B29C48/76
Filed: 1983-01-21
Abstract: PURPOSE:To purify a crude polymer without contamination with foreign matter, by discharging a contaminating polymer from a position near the screw support of a vented-screw devolatilizing extruder and discharging volatile impurities and part of the polymer from the vent. CONSTITUTION:A crude methyl methacrylate- or styrene-based polymer containing volatile impurities is introduced into a feed inlet 6. The screw has flights of different directions on the left and right sides, so that foreign matter such as friction pieces at the screw support 4 can be discharged from an exit 8 and foreign matter at the support 5 is discharged from an exit 9. Therefore the purified polymer leaving an exit 7 is completely freed from any foreign matter. In addition, each of the vents 1 and 2 is on a side and has a descending slope, so that the vent gas can be easily discharged and at the same time the polymer entrained with the vapor of the impurities is also discharged. Thus, the polymer in the purification apparatus will never be contaminated with degraded polymer or the like.

Abstract: PURPOSE:To eliminate the production of a stepwise surface on a boundary by employing an etchant of phosphoric acid series as an etchant when a compound semiconductor made of GaAlAs having different mixed crystal ratio of aluminum is etched, thereby equalizing the etching velocity. CONSTITUTION:An n type layer 3, an n type layer 4, an active layer 5, and a p type layer 6 are laminated on an n type GaAs substrate 1, and a liquid epitaxial growth is then achieved.

Therefore, when it is etched to form the desired mesa structure, a phosphoric acid series etchant containing an ethylene glycol, a hydrogen peroxide and a phosphoric acid is selectively used. In this manner, the etching velocity becomes equal, and no stepwise surface is produced at the mesa boundary.
